Description

Technical Field

[0001] This utility model relates to the field of bar production technology, specifically to an adjustable roller conveyor adapted to the production of bars of any fixed length. Background Technology

[0002] The production of sizing bars (also known as sizing bars or fixed-length bars) typically involves a series of complex metallurgical and processing procedures aimed at transforming raw materials (such as steel or aluminum alloys) into bars with specific lengths, cross-sectional dimensions, and material properties.

[0003] A rail length-setting device (announcement number: CN222199776U) disclosed in the public notice includes a base, a gantry frame, a lifting hydraulic cylinder, a lifting support, a lifting roller, a geared motor, a main bearing seat, a drive roller, a drive roller bearing seat, and a lifting roller bearing seat. The gantry frame is fixedly connected to the base. Both ends of the drive roller are mounted on the drive roller bearing seats, which are connected to the base. The geared motor is connected to the drive roller. A lifting roller is located above the drive roller and is mounted on a lifting roller bearing seat. The lifting roller bearing seat is fixed to the lifting support. The lifting support is connected to the piston rod of the lifting hydraulic cylinder and is slidably connected to the gantry frame. The advantages are: reduced manual intervention in the length-setting process, improved work efficiency, increased product yield, and the ability to meet the production needs of rails of any length and specification.

[0004] The aforementioned patents achieve the effect of lifting hydraulic cylinders driving lifting rollers and active rollers to transport steel rails through devices such as lifting brackets, lifting rollers, and reduction motors. However, they cannot achieve the effects of dynamic avoidance, high adaptability, and strong stability. Therefore, we propose an adjustable roller conveyor that can adapt to the production of bars of any length. Utility Model Content

[0005] This invention proposes an adjustable roller conveyor adapted to the production of bars of any length, solving the problem in related technologies that cannot achieve dynamic avoidance, high adaptability, and strong stability.

[0006] According to one aspect, at least one embodiment of this disclosure provides an adjustable roller conveyor adapted to the production of bars of arbitrary lengths, comprising: a roller conveyor frame, a fixed wheel set fixedly connected to the bottom of the roller conveyor frame, a locking device fixedly connected to the top of the roller conveyor frame, and a frame lateral adjustment device provided on the side of the roller conveyor frame.

[0007] The frame lateral adjustment device includes a fixed frame, the side of which is fixedly connected to the side of the roller conveyor frame. A base is provided on the side of the roller conveyor frame, a motor is fixedly connected to the top of the base, and a bevel gearbox is fixedly connected to the top of the base. A first bevel gear is fixedly connected to the output shaft of the motor. A threaded rod is threaded through the side of the bevel gearbox, a second bevel gear is fixedly connected to the circumferential surface of the threaded rod, a threaded sleeve is threaded to the circumferential surface of the threaded rod, a fixed plate is fixedly connected to the circumferential surface of the threaded sleeve, a screw is bolted to the side of the fixed plate, a limiting rod is bolted to the circumferential surface of the screw, a connecting rod is fixedly connected to the side of the bevel gearbox, and a stop is fixedly connected to one end of the connecting rod. This device achieves dynamic avoidance, high adaptability, and strong stability, ensuring stability and precision during operation. This adjustment device is particularly suitable for mechanical systems requiring precise lateral adjustment.

[0008] For example, in at least one embodiment of this disclosure, an adjustable roller conveyor adapted to the production of bars of arbitrary length is provided, further comprising: the top of the fixed frame is fixedly connected to the circumferential surface of the threaded sleeve, and the first bevel gear meshes with the second bevel gear. The connection between the fixed frame and the threaded sleeve ensures the stability of the threaded sleeve, while the meshing of the first bevel gear and the second bevel gear enables the power of the motor to be accurately and efficiently converted into the rotation of the threaded rod through the transmission system, thereby achieving precise lateral adjustment of the roller conveyor frame.

[0009] The side of the vehicle stop is located on the displacement trajectory of the limiting rod, and there are two limiting rods and screws. The vehicle stop constrains its movement trajectory through the position of the limiting rod, ensuring precise adjustment of the device; while setting two limiting rods and screws can enhance the stability of the device, distribute force evenly, improve accuracy, and at the same time play a safety limiting role, preventing instability or deviation of the equipment during the adjustment process.

[0010] The two screws and limiting rods are symmetrical about the longitudinal axis of the threaded rod, and the bottom of the base contacts the ground. The symmetrical arrangement of the screws and limiting rods ensures the balance and accuracy of the device under force, avoiding tilting or errors; while the contact between the base and the ground provides stable support for the entire device, preventing external interference from affecting the adjustment accuracy and working status of the equipment.

[0011] There is a gap between the bottom of the fixing plate and the top of the fixing frame, and a gap between one end of the threaded rod and the side of the vehicle stop. The gaps between the fixing plate and the fixing frame, and between the threaded rod and the vehicle stop, mainly serve to reduce friction, prevent jamming, provide freedom for thermal expansion, alleviate stress concentration, facilitate adjustment and maintenance, and also provide fault tolerance for the system, thereby ensuring that the equipment can operate smoothly and efficiently.

[0012] According to another aspect, at least one embodiment of this disclosure also provides an adjustable roller conveyor adapted to the production of bars of arbitrary lengths, comprising: an equipment maintenance device provided on the circumferential surface of the threaded rod, the equipment maintenance device including a half gear fixedly connected to the circumferential surface of the threaded rod; a toothed rod slidably connected to the bottom inner side of the bevel gear box; a striking rod fixedly connected to the side of the toothed rod; an oil pump box fixedly connected to the bottom inner side of the bevel gear box; a piston slidably connected to a force-bearing rod at one end of the oil pump box; and an oil outlet pipe fixedly connected to the other end of the oil pump box. The main function of this device is to provide continuous lubrication to the equipment through the oil pump system, reduce wear on mechanical parts, ensure normal operation of the equipment, and extend its service life.

[0013] For example, at least one embodiment of this disclosure provides an adjustable roller conveyor adapted to the production of bars of any length, which further includes: a return spring fixedly connected to the circumferential surface of the force-bearing rod, one end of the return spring being fixedly connected to one end of the oil pump box. The function of the return spring in the system is to provide restoring force, ensuring that the force-bearing rod can return to a predetermined position after being subjected to external force, maintaining the balance and stable operation of the system, and regulating and controlling the flow of lubricating oil, thereby improving the reliability of the equipment and extending its service life.

[0014] One end of the force-bearing rod is located on the displacement trajectory of the impact rod, and the half gear meshes with the rack. This design helps transmit power, control the flow of lubricating oil, and ensures that all parts of the equipment work together by coordinating the movement of the force-bearing rod, impact rod, half gear, and rack, thus playing a role in equipment maintenance, lubrication, and control.

[0015] A spring is fixedly connected to the side of the impact rod, and one end of the spring is fixedly connected to one end of the oil pump housing. The combination of the spring and the impact rod can effectively achieve multiple functions such as buffering, recovery, vibration suppression, and pressure regulation. This design helps to enhance the stability, durability, and working efficiency of the oil pump housing and the entire equipment system, prevent mechanical parts from being damaged by excessive impact or unstable forces, and also improve the safety and reliability of the system.

[0016] The initial state of the return spring is relaxed, and the initial state of the spring is also relaxed. Designing both the return spring and the spring to be in a relaxed state effectively reduces unnecessary friction, prestress, and energy loss, while ensuring the system can respond flexibly and remain stable under external forces. This design helps improve the performance of the mechanical system, extend its service life, reduce maintenance costs, and ensure operational accuracy and reliability.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. This utility model achieves its functionality through the coordinated operation of components such as a motor, threaded rod, threaded sleeve, fixed plate, bevel gear one, and limiting rod. When the motor is started, its output shaft drives bevel gear one to rotate. The rotation of bevel gear one drives bevel gear two, which in turn drives the threaded rod. The rotation of the threaded rod causes the threaded sleeve to move horizontally under the constraint of the roller conveyor frame. The horizontal movement of the threaded sleeve drives the fixed frame to move horizontally, which in turn drives the roller conveyor frame to move horizontally via the fixed wheel set. This achieves the device's dynamic avoidance, high adaptability, and strong stability, ensuring stability and precision during operation. This adjustment device is particularly suitable for mechanical systems requiring precise lateral adjustment.

[0019] 2. This utility model achieves its purpose through the coordinated operation of components such as a motor, bevel gear one, bevel gear two, half gear, threaded rod, and oil pump box. When the motor is started, its output shaft drives bevel gear one to rotate. The rotation of bevel gear one drives bevel gear two, which in turn drives the threaded rod. The threaded rod then drives the half gear, which in turn drives the meshing rack to move horizontally. This horizontal movement of the rack drives a striker to move horizontally, which in turn pushes a piston-like motion within the oil pump box. This motion forces the lubricating oil in the oil pump box to be sprayed out through the oil outlet pipe, lubricating and maintaining bevel gear one and bevel gear two. This achieves the effect of maintaining the equipment and extending its service life. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, it illustrates an adjustable roller conveyor adapted to the production of bars of any length in one embodiment of the present disclosure, comprising: a roller conveyor frame 1, a fixed wheel set 2 fixedly connected to the bottom of the roller conveyor frame 1, a locking device 3 fixedly connected to the top of the roller conveyor frame 1, and a frame lateral adjustment device 4 provided on the side of the roller conveyor frame 1.

[0032] The frame lateral adjustment device 4 includes a fixed frame 41, the side of which is fixedly connected to the side of the roller conveyor frame 1. A base 42 is provided on the side of the roller conveyor frame 1. A motor 43 is fixedly connected to the top of the base 42. A bevel gear box 44 is fixedly connected to the top of the base 42. A bevel gear 45 is fixedly connected to the output shaft of the motor 43. A threaded rod 46 is threaded through the side of the bevel gear box 44. A bevel gear 47 is fixedly connected to the circumferential surface of the threaded rod 46. A threaded sleeve 48 is threadedly connected to the circumferential surface of the threaded rod 46. A fixed plate 49 is fixedly connected to the circumferential surface of the threaded sleeve 48. A screw 410 is bolted to the side of the fixed plate 49. A limiting rod 411 is bolted to the circumferential surface of the screw 410. A connecting rod 412 is fixedly connected to the side of the bevel gear box 44. A stop 413 is fixedly connected to one end of the connecting rod 412. This device achieves dynamic avoidance, high adaptability, and strong stability, ensuring stability and accuracy during operation. This adjustment device is particularly suitable for mechanical systems that require precise lateral adjustment.

[0033] In some examples, the top of the fixed frame 41 is fixedly connected to the circumferential surface of the threaded sleeve 48, and bevel gear 45 meshes with bevel gear 47. The connection between the fixed frame 41 and the threaded sleeve 48 ensures the stability of the threaded sleeve 48, while the meshing of bevel gear 45 and bevel gear 47 enables the power of the motor 43 to be accurately and efficiently converted into the rotation of the threaded rod 46 through the transmission system, thereby achieving precise lateral adjustment of the roller frame 1.

[0034] The side of the stop 413 is located on the displacement trajectory of the limiting rod 411. There are two limiting rods 411 and screws 410. The stop 413 constrains its movement trajectory by the position of the limiting rod 411, ensuring precise adjustment of the device. The two limiting rods 411 and screws 410 can enhance the stability of the device, distribute the force evenly, improve accuracy, and at the same time play a safety limiting role, preventing instability or deviation of the equipment during the adjustment process.

[0035] The two screws 410 and the limiting rod 411 are symmetrical about the longitudinal axis of the threaded rod 46, and the bottom of the base 42 is in contact with the ground. The symmetrical arrangement of the screws 410 and the limiting rod 411 ensures the balance and accuracy of the device under force, avoiding tilting or errors; while the contact of the base 42 with the ground provides stable support for the entire device, preventing external forces from affecting the adjustment accuracy and working status of the equipment.

[0036] There is a gap between the bottom of the fixing plate 49 and the top of the fixing frame 41, and a gap between one end of the threaded rod 46 and the side of the stop 413. The gaps between the fixing plate 49 and the fixing frame 41 and between the threaded rod 46 and the stop 413 mainly serve to reduce friction, prevent jamming, provide freedom for thermal expansion, alleviate stress concentration, facilitate adjustment and maintenance, and also provide fault tolerance for the system, thereby ensuring that the equipment can operate smoothly and efficiently.

[0037] For example, such as Figures 1-5 As shown, when the motor 43 is started, the output shaft of the motor 43 drives the first bevel gear 45 to rotate. The rotation of the first bevel gear 45 drives the second bevel gear 47, which meshes with it, to rotate. The rotation of the second bevel gear 47 drives the threaded rod 46 to rotate. The rotation of the threaded rod 46 drives the threaded sleeve 48 to move horizontally under the restriction of the roller frame 1. The horizontal movement of the threaded sleeve 48 drives the fixed frame 41 to move horizontally. The horizontal movement of the fixed frame 41 drives the roller frame 1 to move horizontally through the fixed wheel set 2. The horizontal movement of the threaded sleeve 48 drives the fixed plate 49 to move horizontally. The horizontal movement of the fixed plate 49 drives the screw 410 to move horizontally. The horizontal movement of the screw 410 drives the limiting rod 411 to move horizontally. When the movement of the threaded sleeve 48 is about to exceed the range of motion, the limiting rod 411 is blocked by the vehicle stop 413, and the threaded sleeve 48 can no longer move horizontally.

[0038] like Figures 1-5 As shown, this illustrates an adjustable roller conveyor adapted for the production of bars of arbitrary lengths, in another embodiment of this disclosure. It is largely the same as the technical solution described above, so only the differences are emphasized. These differences include: a maintenance device 5 is provided on the circumferential surface of the threaded rod 46; the maintenance device 5 includes a half-gear 51 fixedly connected to the circumferential surface of the threaded rod 46; a toothed rod 52 is slidably connected to the bottom inner side of the bevel gear box 44; a striking rod 53 is fixedly connected to the side of the toothed rod 52; an oil pump box 54 is fixedly connected to the bottom inner side of the bevel gear box 44; a force-bearing rod 55 is slidably connected to one end of the oil pump box 54; and an oil outlet pipe 56 is fixedly connected to the other end of the oil pump box 54. The main function of this device is to provide continuous lubrication to the equipment through the oil pump system, reducing wear on mechanical parts, ensuring normal operation of the equipment, and extending its service life.

[0039] In some examples, a return spring 57 is fixedly connected to the circumferential surface of the force-bearing rod 55, with one end of the return spring 57 fixedly connected to one end of the oil pump housing 54. The function of the return spring 57 in the system is to provide restoring force, ensuring that the force-bearing rod 55 can return to its predetermined position after being subjected to external force, maintaining the balance and stable operation of the system, and regulating and controlling the flow of lubricating oil, thereby improving the reliability of the equipment and extending its service life.

[0040] One end of the force-bearing rod 55 is located on the displacement trajectory of the impact rod 53, and the half gear 51 meshes with the rack 52. This design helps to transmit power, control the flow of lubricating oil, and ensure the coordinated work of all parts of the equipment by coordinating the movements of the force-bearing rod 55, the impact rod 53, the half gear 51, and the rack 52, thus playing a role in equipment maintenance, lubrication, and control.

[0041] A spring 58 is fixedly connected to the side of the impact rod 53, and one end of the spring 58 is fixedly connected to one end of the oil pump housing 54. The combination of the spring 58 and the impact rod 53 can effectively achieve multiple functions such as buffering, recovery, vibration suppression, and pressure regulation. This design helps to enhance the stability, durability, and working efficiency of the oil pump housing 54 and the entire equipment system, prevent mechanical parts from being damaged by excessive impact or unstable forces, and also improve the safety and reliability of the system.

[0042] The initial state of both return spring 57 and spring 58 is relaxed. Designing the initial state of both return springs 57 and 58 to be relaxed effectively reduces unnecessary friction, prestress, and energy loss, while ensuring the system can respond flexibly and remain stable under external forces. This design helps improve the performance of the mechanical system, extend its service life, reduce maintenance costs, and ensure operational accuracy and reliability.

[0043] For example, such as Figures 1-5 As shown, when motor 43 is started, the output shaft of motor 43 drives bevel gear 45 to rotate. The rotation of bevel gear 45 drives bevel gear 47, which meshes with it, to rotate. The rotation of bevel gear 47 drives threaded rod 46 to rotate. The rotation of threaded rod 46 drives half gear 51 to rotate. The rotation of half gear 51 drives rack 52, which meshes with it, to move horizontally. The horizontal movement of rack 52 drives impact rod 53 to move horizontally. The horizontal movement of impact rod 53 pushes force rod 55 to move like a piston in oil pump box 54, pushing the lubricating oil in oil pump box 54 to be sprayed out through oil outlet pipe 56 to lubricate and maintain bevel gear 45 and bevel gear 47. When half gear 51 rotates to the toothless position, force rod 55 loses thrust and is horizontally reset by return spring 57. Spring 58 drives impact rod 53 to move horizontally reset by its own elasticity. The reset of impact rod 53 drives rack 52 to reset, waiting for the next operation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
